If an object X is serialized and you perform modifications then you can ensure that the serialVersionUID matches the first one and can thereby decieve the JVM.
There are limits altering logic is acceptable but removing fields is not.

Calculate the default serialVersionUID of an object with http://jsourcery.com/output/sourceforge/javaassist/3.0/javassist/SerialVersionUID.html
